Global public debt is growing faster than before the pandemic in 80% of the world's economies, according to the International Monetary Fund's latest fiscal report. The IMF warns that debt could reach 100% of global GDP by the end of this decade if current growth rates persist.

This surge comes against a backdrop of heightened geopolitical and economic uncertainty, which the fund says could undermine global financial stability. The report underscores the challenges governments face in balancing fiscal responsibility with the need for continued investment.

The IMF's projection is based on current debt trajectories and does not account for potential policy changes or economic shocks. It highlights the structural pressure public finances are under, with many nations still grappling with post-pandemic spending.

For investors and policymakers, the report serves as a warning about the fragility of sovereign balance sheets. Rising debt levels could constrain government spending on critical areas like infrastructure or social programs, potentially slowing economic growth.

Some analysts argue, however, that public investment in science and innovation can boost long-term productivity, offsetting debt concerns over time.
